The Despatch LAC2-12 is a Class A batch oven for industrial heating, testing, preheating, sterilizing, drying, aging, and curing applications. It delivers precise temperature control to ±0.5°C repeatability with horizontal recirculating airflow ensuring uniform heat distribution across the 20″ H × 24″ W × 24″ D workspace. The double-wall stainless steel construction with 3 inches of fiberglass insulation minimizes thermal loss while maintaining temperature stability of ±0.5°C per 5°C ambient variation.
